   INSPECT CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY

   
   

   1. Measure the resistance according to the value(s) in the table below.

      Standard Resistance
      Tester Connection Condition Specified Condition 1 - 2 20°C (68°F) 6.9 to 7.9 Ω

      If the result is not as specified, replace the camshaft timing oil control valve assembly.

   2. 

      Connect a positive (+) lead from the auxiliary battery to terminal 2 and a negative (-) lead to terminal 1, and check the movement of the valve.

      Table 1. Text in Illustration

      *1	Valve
      *a	Component without harness connected (Camshaft Timing Oil Control Valve Assembly)
      *b	When applied
      *c	When cut off

      OK
      Condition Specified Condition Auxiliary battery voltage is applied Valve moves in left arrow direction shown in illustration Auxiliary battery voltage is cut off Valve moves in right arrow direction shown in illustration

      Note:

      Confirm that the valve moves freely and does not stick in any position.

      If necessary, replace the camshaft timing oil control valve assembly.

      Tip:

      Accumulation of foreign matter can cause minor pressure leaks. Minor pressure leaks will cause the camshaft to advance or retard, and this will cause a DTC to be set.
